Have you tried to play with 'order' of starting of device,first Q7 then Master7 and vice versa?
Or may be a problem with the operating system.
Although for some time I have been ogling Ian Canada's modules and ploughing through this bounteous thread, this is my first post here. I think I am ready to take the plunge, and to start with a streamer with I2S output, for which I would use the RPi4 that is now in my Pi2AES.
Before ordering, I would appreciate any comments on my current shopping list:
Newbee question: is it correct that all RPi based DAC projects here are actually integrated streamer/DAC combo's? If yes, would that bring SQ benefits compared to using a separate streamer, due to shorter/simplified connections? No need in that case for an HDMI/I2S cable for instance.
Before ordering, I would appreciate any comments on my current shopping list:
- StationPi Pro
- FifoPi Q7
- HDMIPi Pro
- PurePi II
- 2x batteries 18650
- UcConditioner 3.3V
- 2 ultracapacitors

Not yet. I went to that site a there were a million pop ups and I was scared to click on anything.
I went opposite with separate streamer. The DAC stack has no RPi. So that means less noise. I2S is digital. I’m finding no quality loss from streamer to DAC. I think Ian’s recent post on ReciverPiDDC also endorses this approach if you read it.
Indeed I see advantages of separating streamer and DAC, keeping the DAC noise free, and also being able to be able to compare them with other streamers/DACs. On the other hand, combining them in one stack (or two when integrated by the StationPi Pro), would be considerably more cost effective, f.i. making the HDMIPi and ReceiverPi redundant.
On another topic: is there a table somewhere that shows the correlation of possible/maximum resolutions (PCM 44-384 and DSD 64-512) and clock frequencies (22.5792, 24.5760, 45.1584, 49.1520)? I searched for it but just found some conflicting information.
No, I didn't connect the q7 from UFL, as the center UFL wire is so flimsy that its thinness makes it inconvenient to connect to the DAC connector, and it breaks easily too.
Is there any reason to believe that signals from UFL will be somehow different from FifoPi GPIO pins' signals?

Hi. I am looking to build this DAC. I was wondering if anyone could please help me out with a couple of questions.
Do I have to buy the Amanero Combo384 Module and remote separately or does Ian sell them as well?
It says in the manual "Possible upgrade: - Upgrade the 3.3V power supply to a PurePi MkIII 3.3V" Is that a typo? I can only find info on PurePi MkII and no PurePi MkIII.
Is the I/V pictured with the round transformers the new version of the OPA861 I/V? Does it need to be supplied +-5v power?

Thank you for the clue.
I'm a little surprised that there is no such setting in the FifoPi Q7 controller itself, if without this option its functioning is impossible.
In the manual for MonitorPI I can't see a single hint of such an option or description of its change too.
How do you transfer a digital stream from FifoPi Q7 to your Audio-Gd R7 He Mk2? I mean, do you use any interface or feed i2s directly?

Yes but you would need the DAC board and it becomes a DAC and a DDC but that is commonly called a DAC.
Analogue output needs DAC board. The AES and the HDMI are digital outputs.
Ian does not sell the Amanero.
There is a linear pi duo I use to power my analogue output OPA861IV differential voltage.
I don’t recognize that IV board. Check below….for IV boards.

Not sure

No these are transformers by Ivan instead of Opa861 you do not need power -5 0 +5v with transformers see one of my videos where I compared the 2.

Not sure. Haven't seen a comparison of different USB modules reclocked through a FIFOPi Q7. To easily work with Ian's stuff it minimally needs a header compatible with the Amanero Combo 384 module. It is cheaper in the US to get a chinese Xmos with a compatible header than to order the Amanero from Italy.
